Safety Functions

13.2.5.1 Actuator and Braking element for UCM
If the machine brake built due to EN81-20 §5.9.2.2.2, the machine brake may be the braking element for
UCM. Therefore, the eSGC-actuator is not necessarily needed with regard to UCM.
If the machine brake is not built due to EN81-20 §5.9.2.2.2, a brake, which is not needed for controlling the
speed in normal lift operation, must be the braking element for UCM. This may be

An electronic trigger-able safety gear

A conventional safety gear tripped by speed governor. This speed governor again is tripped by a block-
ing device (remote tripping) connected to eSGC.

A rope gripper
The tripping coil of this braking element must be connected to the eSGC-actuator.
13.2.6 Safety Functions in EN81-21 State
13.2.6.1 Activation of EN 81-21 State
LIMAX33 CP-00 fulfills safety functions in order to protect a man in the pit on the car roof or elsewhere in the
shaft for maintenance work.
These safety functions are activated in case of EN81-21-state. EN81-21 state is activated if the EN81-21-signal
(input) is active. An open input or LOW level means “active”, 24 V on the input means “not active”.
The following subchapters define those safety functions which depend on the EN81-21-state.
13.2.6.2 Overspeed Inspection (Pre-Tripping)
OC opens, if there is actual EN81-21-state and speed exceeds “pre-tripping speed inspection”. “Pre-tripping
speed inspection” is a fixed configuration parameter

14.1
This safety function is reset (and therefore OC closes) in case standstill is reached and hold for 1s.
13.2.6.3 Overspeed Inspection (Final Tripping)
eSGC opens additional to OC, if there is actual EN81-21-state and speed exceeds “final-tripping speed inspec-
tion”. “final-tripping speed inspection” is a fixed configuration parameter

14.1
After tripping of this safety function, eSGC and OC are kept open even after stand still. This state is stored in a
non-volatile way: eSGC and OC will also kept open after a power cycle. This state is cleared by manual reset
(by CANopen).
SR1 and SR2 are already open due to EN81-21-state
13.2.6.4 Actuator and Braking element for Overspeed Inspection (Final Tripping)
The braking element for Overspeed inspection (final tripping) may be:

An electronic trigger-able safety gear

A conventional safety gear tripped by speed governor. This speed governor again is tripped by a block-
ing device (remote tripping) connected to eSGC.

A rope gripper
The tripping coil this braking element must be connected to the eSGC-actuator.
